ABSTRACT

BACKGROUND: The Milan criteria are used to select candidates with small hepatocellular carcinoma (HCC) for liver transplantation. Due to severe shortage of donors, majority of patients within the Milan criteria need to seek alternative treatments. AIM: To propose a prognostic model for these patients undergoing non-transplant therapies. METHODS: A total of 1106 HCC patients, who were within the Milan criteria and received non-transplant therapies were retrospectively analysed. Patients were randomly assigned to the derivation and validation set according to treatments. A prognostic model was constructed from independent predictors of survival identified in the multivariate Cox model of the derivation set and was confirmed in the validation set. RESULTS: In the Cox model, serum bilirubin ≥1.5 mg/dL [risk ratio (RR): 1.525, P = 0.016], α-fetoprotein (AFP) ≥100 ng/mL (RR: 1.728, P < 0.001), mild ascites (RR: 1.705, P = 0.025) and moderate/severe ascites (RR: 4.163, P < 0.001) were independent predictors of poor survival in the derivation set (n = 553). A prognostic model with a total of 0-4 points was derived with the sum of three variables: 1 point each for bilirubin ≥1.5 mg/dL, AFP ≥100 ng/mL and mild ascites, and 2 points for moderate/severe ascites. This scoring system accurately predicted the survival in the validation set (n = 553; P < 0.001). The model consistently discriminated the survival in patients stratified by curative and noncurative treatments (both P values <0.001). CONCLUSION: The newly proposed prognostic scoring model, based on serum bilirubin and AFP level, and severity of ascites, is informative to predict the survival in non-transplant HCC patients within the Milan criteria.

ABSTRACT

AIMS: To evaluate the clinical inference of serum alpha-fetoprotein (AFP) response in hepatocellular carcinoma (HCC) patients undergoing percutaneous radiofrequency ablation (RFA). MATERIALS AND METHODS: Three hundred and thirteen previously untreated HCC patients were enrolled in the study. The optimal AFP response was defined as >20% decrease from baseline after 1 month of RFA for those with a baseline AFP level of ≥100 ng/ml. The impact of AFP response on prognosis was analysed and prognostic factors were assessed. RESULTS: After a median follow-up of 26.7 ± 19.1 months, 49 patients died and 264 patients were alive. The cumulative 5 year survival rates were 75.3 and 57.4% in patients with an initial AFP of <100 ng/ml and ≥100 ng/ml, respectively (p = 0.003). In the 58 patients with a baseline AFP of ≥100 ng/ml and initial completed tumour necrosis after RFA, the cumulative 5 year survival rates were 62.4 and 25.7% in optimal and non-optimal AFP responders, respectively (p = 0.001). By multivariate analysis, the prothrombin time international normalized ratio >1.1 (p = 0.009), non-optimal AFP response (p = 0.023), and creatinine >1.5 mg/dl (p = 0.021) were independent risk factors predictive of poor overall survival. Besides, the cumulative 5 year recurrence rates were 83.4 and 100% in optimal and non-optimal AFP responders, respectively (p < 0.001). Multivariate analysis demonstrated platelet count ≤10(5)/mm(3) (p = 0.048), tumour size >2 cm (p = 0.027), and non-optimal AFP response (p < 0.001) were independent risk factors associated with tumour recurrence after RFA. CONCLUSIONS: Serum AFP response may be a useful marker for predicting prognosis in HCC patients undergoing RFA.

ABSTRACT

BACKGROUND AND AIM: Serum sodium has been suggested to incorporate into the model for end-stage liver disease to enhance its prognostic ability for cirrhosis. A mathematical equation based on model for end-stage liver disease and sodium, known as "MELD-Na", was developed for outcome prediction for cirrhosis. The severity of liver cirrhosis is a key component to predict survival in patients with hepatocellular carcinoma. This study investigated the prognostic role of MELD-Na for hepatocellular carcinoma. PATIENTS AND METHODS: A total of 535 unselected hepatocellular carcinoma patients were prospectively enrolled to evaluate the performance of MELD-Na. RESULTS: The MELD-Na was better than model for end-stage liver disease in predicting 6-month mortality by comparing the area under receiver operating characteristic curve (0.782 vs. 0.761, p=0.101). MELD-Na, but not model for end-stage liver disease, was an independent predictor associated with 6-month mortality in multivariate logistic regression analysis (odds ratio: 1.14, p=0.001). In the survival analysis, MELD-Na also independently predicted mortality, with an additional risk of 4.3% per unit increment of the score (p<0.001). Patients with MELD-Na scores between 10 and 20 and scores >20 had 2.1-fold (p<0.001) and 7.5-fold (p<0.001) risk of mortality, respectively, compared to patients with a score <10 in the Cox proportional hazard model. CONCLUSION: The MELD-Na score is a feasible and independent prognostic predictor for both short- and long-term outcome predictions in patients with hepatocellular carcinoma.

ABSTRACT

A 14-year old girl with lupus erythematosus (LE) who initially showed as discoid lupus and followed with nephrotic syndrome one year later. Concomitant piroxicam and indomethacin were prescribed for her arthritis, which preceded two months before the onset of nephrotic syndrome. Histology from renal biopsy showed minimal-change nephrotic syndrome (MCNS). After continuous treatment for six months, nephrotic syndrome resolved completely and no signs of relapse were noted over 14 years of follow-up. For the children, it is rare to have both LE and MCNS simultaneously; sequela of nonsteroidal anti-inflammatory drugs also seldom results in nephrotic syndrome. Though their relationship is still not defined, the possibility of LE combined with MCNS must be differentiated in patients with lupus and severe proteinuria.

ABSTRACT

Unilateral ureteral obstruction (UUO) is a well-characterized hydronephrosis model exhibiting interstitial inflammatory-cell infiltration and tubular dilatation followed by tubulointerstitial fibrosis of the obstructed kidney. Our recent report indicates that rapamycin is effective for 50% of transplant recipients with chronic allograft nephropathy. In this study, we investigate the effect of rapamycin on UUO-induced renal fibrosis. UUO or sham-operated rats were randomly assigned to rapamycin or vehicle and were killed on days 7 and 14 after UUO or sham operation. Rapamycin decreased cross-sectional and gross-morphology changes in the obstructed kidney significantly. Rapamycin markedly blunted the increase in weight of the obstructed kidney, obstructed kidney length, and the obstructed/non-obstructed kidney weight ratio (by 74.6, 42.8, and 61.6% on day 14, respectively, all P<0.01). The scores for tubular dilatation, interstitial volume, interstitial collagen deposition, and alpha-smooth muscle actin (alpha-SMA) after UUO were significantly reduced by rapamycin. Rapamycin also decreased the number of infiltrative anti-ED1-positive cells and the gene expression of transforming growth factor (TGF)-beta1 (84.8 and 80.2% on day 7) after UUO (both P<0.01). By double immunostaining and Western analysis, rapamycin blocked the TGF-beta1-induced loss of E-cadherin expression and de novo increase of the expression of alpha-SMA in a dose-dependent manner. In conclusion, rapamycin significantly attenuated tubulointerstitial damage in a UUO-induced rat model of renal fibrosis, suggesting that rapamycin may have the potential to delay the progression of tubulointerstitial renal fibrosis.

ABSTRACT

(99m)Tc dimercaptosuccinic acid (DMSA) renal scans can provide accurate diagnosis of acute pyelonephritis, its sequelae (renal scars) and differential renal function (DRF). The purposes of this retrospective study were (1) to assess the relationship between DRF obtained during acute pyelonephritis and at follow-up, and (2) to elucidate the value of initial DRF in predicting subsequent renal scars. A total of 47 children were enrolled. All had both unilateral acute pyelonephritis diagnosed by initial DMSA renal scans, and follow-up DMSA renal scans. We found the correlation between initial and follow-up DRF poor (adjusted R2 = 0.396). Whether or not renal scars developed determined the follow-up DRF. Vesicoureteral reflux was significantly more common in children who developed renal scars. In addition, the higher the grade of vesicoureteral reflux, the lower the follow-up DRF and the improvement in DRF. When using a DRF of 46% as the cut-off value to predict subsequent renal scars, the sensitivity and specificity were 47.8% and 83.3%, respectively. Owing to the low sensitivity, initial DRF is not suitable for predicting the occurrence of renal scars.

ABSTRACT

PURPOSE: To evaluate whether acute pyelonephritis lesion volume derived from acute technetium 99m ((99m)Tc) dimercaptosuccinic acid (DMSA) renal single photon emission computed tomographic (SPECT) images is predictive of the development of subsequent renal fibrosis. MATERIALS AND METHODS: Children with acute pyelonephritis underwent (99m)Tc DMSA renal SPECT during acute infection and 6-10 months later. At quantitative analysis, the volume of photopenic lesions and the ratio of radioactivity in the photopenic lesion to that in normal renal tissue were calculated. Sensitivity, specificity, and positive and negative predictive values were determined. RESULTS: Sixty-nine acute pyelonephritis foci in 44 children were analyzed. Thirty-seven (54%) of these lesions were normal on follow-up renal scans, while 32 (46%) developed scars. Significant differences in the photopenic lesion volume were found between the two groups (P < .001). When photopenic lesion volume indicated a positive diagnosis (>or=4.6-cm(3) lesion volume), sensitivity, specificity, positive predictive, and negative predictive values were 96.7%, 92.3%, 90.6%, and 97.3%, respectively. CONCLUSION: Quantitative analysis of acute DMSA renal SPECT findings is valuable in predicting renal fibrosis. The volume of an acute pyelonephritis lesion is useful in predicting the development of fibrosis.

ABSTRACT

Catalytic incineration is one of the cost-effective technologies to solve the troublesome VOCs. However, some sulfur containing VOCs, such as ethyl mercaptan and dimethyl disulfide, may deactivate the Pt catalyst that is commonly used in the catalytic incineration process. The catalytic incineration of these compounds over a Pt/Al2O3 catalyst was carried out in a bench scale catalytic incinerator. Three kinetic models, such as power-rate law, Mars and Van Krevelen model, and Langmuir-Hinshelwood model were used to analyze the results. A differential reactor design was used for best fit of kinetic models in this study. The results show that the Langmuir-Hinshelwood model is feasible to describe the catalytic incineration of both C2H5SH and (CH3)2S2. This suggests that the chemical adsorption of O2 molecule is important in the process of catalytic incineration of C2H5SH and (CH3)2S2.

ABSTRACT

Urinary beta-2-microglobulin (beta 2M) and microalbumin concentrations were analyzed in 61 pediatric patients with febrile urinary tract infection (UTI). The results were compared with those of technetium-99m-labeled dimercaptosuccinic acid (99mTc-DMSA) single photon emission computed tomography (SPECT) imaging. Noninvasive evaluations were made to localize the site of the UTI. Increased urinary beta 2M/Creatinine (Cr) or microalbumin/Cr quotients were not associated with renal inflammation, as defined by a positive renal scan. Increased urinary microalbumin/Cr is associated with UTI in febrile patients regardless of the level of infection (scan status), and may be an informative indicator of UTI. When microalbumin/Cr was > or = 0.03, its sensitivity and specificity to predict UTI in febrile patients, regardless of the site of the infection, were 95.65% and 51.79%, respectively, and its positive predictive value was 62.0%. On the other hand, urinary beta 2M/Cr (> or = 0.13) demonstrates a statistically significant correlation with the presentation of a high grade of vesicoureteral reflux (p = 0.02). We suggest that a prompt renal imaging study is warranted when the urinary beta 2M/Cr ratio is high (> or = 0.13).

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate the effect of lifestyle habits on the risk of primary gastric cancer. METHODS: A hospital-based case-control study of matched pairs was conducted in Kaohsiung, Taiwan, from 1992 to 1996. The study included 649 subjects (152 cases and 497 controls). All subjects were personally interviewed face-to-face by a trained interviewer using a structured questionnaire to collect data about lifestyle. An average of approximately three controls were matched to each case based on age (+/-3 yr), sex, and time of hospitalization (+/-2 wk). Adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) were used to evaluate results, and a multivariate analysis of the data was performed using a conditional logistic regression model. RESULTS: A significantly elevated risk of contracting gastric cancer was observed in cigarette smokers (OR: 2.7, 95% CI: 1.5-4.3), but not in drinkers of alcoholic beverages (OR: 1.5, 95% CI: 0.9-3.2). A synergistically augmented relationship (multiplication effect) was found between smoking and drinking alcohol for controlling the major confounders. The combined adjusted ORs for all subjects with gastric cancer were 3.0 (95% CI: 1.4-7.1) for current smokers and 1.7 (95% CI: 1.2-4.4) for ex-smokers. Furthermore, a statistically significant positive dose-response trend in gastric cancer was demonstrated based on the age at which smoking was initiated, the duration of the habit, the number of cigarettes smoked per day, and the degree of smoke inhalation. We did not find any association between the other risk factors and gastric carcinogenesis. CONCLUSIONS: Our findings provide further evidence that in Taiwan, cigarette smoking may play the most harmful role in the initial development of gastric cancer, and that drinking alcohol may promote the process.

ABSTRACT

A 9-year-old girl with nephrotic syndrome visited a local hospital after developing fever, chills, and edematous changes and multiple hemorrhagic bullae on both legs over 2 days. Cultures of blood and an aspirate from the bullae yielded Vibrio vulnificus. The patient was transferred to our hospital because of persistent fever, generalized edema, acute renal failure, and disseminated intravascular coagulopathy. We treated this patient as a V. vulnificus infection complicated with necrotizing fasciitis. With minocycline and ceftazidime combination therapy was instituted. Emergency fasciotomy and continuous peritoneal dialysis were performed. The patient developed acute respiratory distress syndrome (ARDS) during the hospitalization, requiring intubation and mechanical ventilation. She eventually died. The histopathological findings showed diffuse alveolar damage with lobular pneumonitis. Hyaline membranes, composed of proteinaceous exudate and cellular debris, covered the alveolar surfaces. Microscopic examinations of lung could not distinguish the effects of cytolysin from other insults to lungs that occur in ARDS. This report highlights the postmortem pathological findings in V. vulnificus infection in a child with nephrotic syndrome complicated by ARDS.

ABSTRACT

BACKGROUND: Treatment involving photosensitizers and laser irradiation (LIR) in cancer therapy is known as photodynamic therapy (PDT). The purpose of our study was to assess the therapeutic effect of PDT using rhodamine-123 (Rh123) and LIR on subcutaneous tumors (ST) in mice. METHODS: Sarcoma-180 cells (1 x 10(7)) were implanted subcutaneously into the breast area of strain Cr1:CD-1-ICR (BR) female mice. Mice bearing ST were treated with Rh123 or LIR alone, or a combination of both, once a day for 3 successive days. RESULTS: The best therapeutic effect was observed in the group treated with 7.5 mg Rh123 per kilogram of body weight, combined with 75 J/cm2 laser irradiation energy. The group's mortality rate, tumor control rate, mean survival time, and increase in lifespan within 120 days after treatment were 16.7%, 83.3%, 109.4 days, and 135.8%, respectively. The most inhibitory effect on tumor cells was found in the group treated with 15 mg/kg Rh123 and 90 J/cm2 laser irradiation. The biosyntheses of DNA, RNA, and protein in tumor cells of this group was obviously inhibited. CONCLUSION: PDT with the photosensitizer Rh123 and laser irradiation was therapeutically effective in treating subcutaneous tumors of mice. The tumor cells and the syntheses of DNA, RNA, and protein of the tumor cells in these PDT treated mice were obviously inhibited.

ABSTRACT

BACKGROUND: For both animals and human beings, it is important to prevent damage from ionizing radiation and to restore immunocompetence following irradiation. The present study was conducted to investigate the effects of glycyrrhizae (GL) and glycyrrhetinic acid (GA) on cellular immunocompetence in low dose gamma-ray-irradiated mice. METHODS: Six- to 8-week-old ICR strain' Crl:CD-1-ICR (BR) strain male mice, bred in the Institute of Cancer Research, U.S.A., were chosen and divided into four groups. Group A was the normal control. Group B, the experimental control, received 1 Gy of whole body gamma-ray irradiation. Groups C and D, the experimental groups, were treated with 500 mg/kg of GL (orally) and 5 mg/kg body weight of GA (i.p.), respectively, once a day, 5 days a week for 2 weeks after gamma-irradiation. The tested mice were killed, at 6 different intervals to measure their leukocyte and differential counts. Cellular immunocompetence was measured by the 3H-thymidine uptake in each group. RESULTS: One gray of gamma-ray irradiation had evident inhibition on the leukocyte and differential counts and the cellular immunity of mice. GL and GA could help to restore the decreased leukocyte counts and the cellular immunocompetence in low dose gamma-irradiated mice. CONCLUSION: GL and GA could help to restore decreased leukocyte counts and the cellular immunocompetence in low-dose gamma-ray-irradiated mice.

ABSTRACT

Intensive care management of the injured child requires a multidisciplinary approach and meticulous attention to detail. However, the overwhelming majority of injured children are cared for by surgeons in surgical intensive care units (ICU) that see both adult and pediatric patients. There have been no previous reports of studies comparing the outcome in surgical ICUs (SICU) dealing with patients of all ages versus the outcome in pediatric ICUs (PICU). This study sought to determine differences in the outcome of pediatric intensive care between the SICU and PICU of our hospital. From Jan. 1989 to Aug. 1995, 118 children (68 boys and 50 girls), with an average age of 9.19 years (range: 3 months to 16 years), were admitted to our SICU. During the same period, 65 children (42 boys and 23 girls), with an average age of 5.04 years (range: 2 months to 16 years), were admitted to our PICU. Most of these patients received surgical intervention and were exclusively under surgeons' management. The decision to admit patient to the SICU or PICU was made by surgeon based on the availability of ICU beds. Pediatric risk of mortality (PRISM) score was used as a scoring system to assess disease severity in children. The most common cause for admission in both ICUs was traffic accidents. The average hospitalization duration in the SICU was 4.06 days (range 1 day to 23 days) and 3.34 days (range 1 day to 17 days) in the PICU. The average PRISM score was 7.87 (range 0-41) in the SICU and 6.48 (range 0-35) in the PICU. The overall mortality rate in the SICU was 12.7% (15/118) and 7.7% (5/65) in the PICU. There was a significant difference in patients' age and operative status but no significant difference in admission duration, PRISM score, and mortality rate between the SICU and PICU groups. The regression coefficients of the selected predictor variables and the impact on outcome showed one more score of PRISM would increase 1.5 fold of risk to become poor outcome while operation had lower risk (0.1 fold) to develop poor outcome. In conclusion, disease diversity and severity were similar among PICU and pediatric SICU patients in this study. The outcome was better in PICU patients although the difference was not statistically significant. The PRISM score is a useful measure to predict poor outcome in ICU patients after adjustment with confounders.

ABSTRACT

Three Chinese girls with hypokalemic periodic paralysis secondary to different types of renal tubular acidosis are presented. One girl has primary distal renal tubular acidosis complicated with nephrocalcinosis. Another has primary Sjögren syndrome with distal renal tubular acidosis, which occurs rarely with hypokalemic periodic paralysis in children. The third has an isolated proximal renal tubular acidosis complicated with multiple organ abnormalities, unilateral carotid artery stenosis, respiratory failure, and consciousness disturbance. The diagnostic evaluation and emergent and prophylactic treatment for these three types of renal tubular acidosis are discussed.

ABSTRACT

An eight-year retrospective study was performed to determine the incidence of peritonitis in a pediatric continuous ambulatory peritoneal dialysis (CAPD) population of 24 children, half of whom were boys and half, girls. All suffered from end stage renal disease (ESRD). When these children, aged 2 through 17 years (mean: 10.7 +/- 3.8), were examined, the incidence of peritonitis was one episode every 15.2 patient-months. Microbiologic evaluation showed that 76.4% of the 34 episodes were culture positive, with Staphylococci species (coagulase negative staphylococci 32.4%, Staphylococcus aureus 14.7%) causing most cases especially early in dialysis. Half the patients presented with a triad of symptoms (fever, abdominal pain and cloudy dialysate), with cloudy dialysate was the major presentation (88%). Peritonitis was treated with intraperitoneal administration of cefacin and/or netromycin when suspected, and 52.9% of the episodes needed hospitalization. Except for two patients who died of complications (sepsis, acute pancreatitis), all episodes of peritonitis were cured; in four episodes it was necessary to remove a catheter, and two of those cases came from fungal peritonitis. Peritonitis rates differed among disconnect systems. The manual spike had peritonitis rate of one episode per 4.6 patient-months which was higher than the O-set (one episode/22.2 patient-months), UV-XD and Y-set disconnect systems. Therefore, the major causes of peritonitis arose from contamination provoked by the technical aspect of the procedure. Nutrition status was stable in these patients. Serum albumin and total protein were adequate in all patients without relation to episode of peritonitis.(ABSTRACT TRUNCATED AT 250 WORDS)

ABSTRACT

Two neonates with a combination of truncus arteriosus and interruption of the aortic arch, so-called type A4 of the Van Praagh classification, are reported. Both presented as tachypnea, poor appetite and increasing cyanosis during the first week of life. The combination of these defects significantly increases the surgical risk. Di-George syndrome was noted in one patient, who presented with hypocalcemia and T cell dysfunction. Autopsy confirmed this diagnosis.
